迈克尔逊干涉实验分析与改进和测量塑料的折射率及优越性 摘  要:本文对迈克尔逊干涉实验中由于操作不当和实验仪器装置引起异常现象进行了分析和处理。先用用迈克尔逊干涉仪测量了激光器激光的波长。以此激光作为光源,并利用零光程差法测量了未知透明塑料板的折射率,这种方法与用激光器光源测量干涉条纹直径的测量方法,用白光作为光源测量方法和用激光器光源并附加一套配套装置的测量方法比较,有精度高、操作简便的优越性。

Analysis and Improvement of the Michelson Interferometer Experiment
Abstract: In this paper, the experiment of Michelson interferometers due to improper operation caused abnormal phenomena were analyzed and the experimental apparatus and process. First the laser wavelength of laser was measured by Michelson interferometer. Laser as a light source, and uses the method of zero optical path difference measuring the refractive index of transparent plastic sheet unknown, this kind of method measurement with  laser light source, interference fringe diameter measurement method, using while light as the light source measurement method and laser light source and attach a supporting device of measurement methods, has the advantages of high accuracy, easy operation.
Key Words: Michelson interferometer; Experimental anomalies; Interference fringe; Refractive index
